Abstract

The invention discloses a modular and expandable microwave switch matrix. The modular and expandable microwave switch matrix comprises two T-shaped microwave switches, a cable assembly and a control circuit, wherein ports of the two T-shaped microwave switches are connected by the cable assembly, the other port used as a matrix input port and the other port used as a matrix output port communicatewith an output end, the remaining port of one of the T-shaped microwave switch communicates with a backup end, the remaining port of the other T-shaped microwave switch communicates with a load and is used as an expansion port, and radio frequency connection switching of arbitrary two paths between two paths of radio frequency input and three paths of radio frequency output of the matrix can be achieved by the control circuit. By optimized integration and switching matching of the T-shaped microwave switches and other parts, the modular and expandable microwave switch matrix has the characteristics of compact structure, low cost, high reliability, high universality, high expandability and the like.

Description

technical field [0001] The invention belongs to the field of microwave switch matrix and relates to a microwave switch matrix. Background technique [0002] In aerospace engineering, microwave switches are widely used to realize routing switching of microwave signal transmission. A typical application case is to use microwave switches to back up key components. In order to improve the overall reliability of the system, redundant backup parts are usually designed for key components. When the working part fails, the faulty part is isolated from the system through the routing control of the microwave switch, and the redundant backup part is connected to the system to work . In order to achieve more complex many-to-many backup requirements, while considering the overall reliability and overall performance of the system, multiple microwave switches are used for link combination in aerospace engineering. A plurality of microwave switches are combined to build a link, that is, a ...
